Abstract

This paper proposes a new execution model for confidentiality and privacy in cloud computing, called the HybrEx (Hybrid Execution) model. The HybrEx model provides a seamless way for an organization to utilize their own infrastructure for sensitive, private data and computation, while integrating public clouds for nonsensitive, public data and computation. We outline how to realize this model in one specific execution environment, MapReduce over Bigtable.
